## Customer Reviews

### ⭐⭐⭐⭐⭐ Super strong and quiet.
*by S***N on September 18, 2024*

This comes with all the cables needed and more. It’s a quality power supply and Corsair stands behind them 100%. I had an issue with an older one in another PC and the RMA’d it back and sent out a replacement without a hassle. This one went into my sons gaming OV and has been running perfectly for months now. I bet it outlives the motherboard and processor. Great buy.

### ⭐⭐⭐⭐⭐ I know Corsair for its quality and good customer support. This yet another good product from them.
*by A***A on December 25, 2022*

Purchased on: November 29, 2016 and reviewed as of January 17, 2023.I have had this power supply for a few years already and I have never had a single issue with it.It is quiet and works very well. It includes plenty of cables that should cover all of your needs.I recently decided to upgrade to a new HX1000i because I am confident in Corsair's quality and I need a new power supply for my 4090. Highly recommended from my personal experience.Unfortunately, I don't have the knowledge to go into technical details for the power supply so I can only share my average end user experience.

### ⭐⭐⭐⭐⭐ Efficient, quiet, and more than enough.
*by C***N on September 7, 2017*

This power supply is probably overkill for me but I wanted a power supply that was completely silent and that will last me through any future upgrade. I never reach loads high enough with the components in my system that the power supply's fan will even spin up and create unwanted noise like my last one. This is one of the highest rated efficient power supplies out there when I bought it, besides the RM1000x, of course. The price seems to fluctuate and balloon ridiculously high often with each of these models. I bought this at around $100, and when I posted this it is up to $150. The RM100x I have seen at $120, now it is somewhere around $175. I can only assume this is because they are in such high demand because of their 'legendary' efficiency ratings by some guy with a website I forgot its name that does all of the testing on power supplies... anyway.It is powering the following and the the fan never spins up besides at boot:AMD Ryzen 1700 OC'ed to 3.9 GHzAsus Prime B350-PlusNvidia GeForce GTX 970Corsair 3000MHz RAM 2x 8 GBCorsair H100i v21 SSD3 HDDIt will run your stuff and it is super quiet.
